Official Description
Incomplete blacklist vulnerability in mainfile.php in PHP-Nuke 7.9 and earlier allows remote attackers to conduct SQL injection attacks via (1) "/**/UNION " or (2) " UNION/**/" sequences, which are not rejected by the protection mechanism, as demonstrated by a SQL injection via the eid parameter in a search action in the Encyclopedia module in modules.php.
Technical Analysis
CVE-2006-5525 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2006-5525. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
